g ANTIGREEPER.

To-allivhom z'tmay concern: i I

Be it known that'I, PHILIP Moons, a

citizen ofthe United States, residing at Evanston, in the county of Cook and State of Illinois, have invented, certain new and useful Improvements in Anticreepers, of which the following is a specification.

My invention relates-to an anti-creeper,

that is, to a device for preventing the longitudinal creep of a railroad rail, and particularly to a type .of device comprising two elements, one having a jaw engaging one edge of the rail base, and theother a similar jawf engaging the opposite edge of the rail base,

each of such elements having a hook or aw which extends around and has a wedging.

engagement with apart of the other element.' The advantage of an anti-creeper of this type is that the movable element, that is, the one standing away from the tie, may be driven into anintimate wedging engagement with the other element so as to produce a very firm, reliable and permanent hold on the rail. a f

One of the principal objects of my present invention is to provide an anti-creeper of this general type which will be lighter, more compact and less cumbersome than the device of the sort heretofore put on the mar-'.

ket, without, however, sacrificing strength or holding power. I i

A further object is to provide in an anticreeper of this type, a form of engagement between the two elements which, because of the contour of the interlocking parts, will minimize the chance ofone of the parts backing away or being shakenloose from the other by vibration-of the rail or other like disturbing influences. f

The invention has for further objects such other new and improved constructions, arrangements and devices relating to. anticreepers as will be hereinafter described and claimed.

The invention is illustrated, in a preferred embodiment, in the accompany ng drawings wherein Figure .1 is a side elevation of the device shown as applied to 'a rail, a portion of the. latter being illustrated in section;' Fig. 2 -isa sectional plan taken on'line 2-2 of Fig. 1. Fig. 3 is a sectional view, on-line 3-3 -of Fig. 2, and Figs. 4 and 5 are views, in per spective, of the two elements or members of which the device is composed.

The anti-creeper, in the preferredembodiment shown, consists of two interlocking elements 'D and E, the former adapted to B, and C one of the ties on which the'rail bear against the tie- C and the latter being driven toward thetie as far as it will go in applying the device to the rail. ,The elemerit D consists preferably of a substan-- ti'ally triangular base 10 having an opening like parts in the several figures of draw Referring to the drawings, A represents ra1l, the base flange of which is designated- 11 cut thereinfor the sake of lightness; a

jaw 12 adapted to engage one edge of the base flange B of rail A, a tie abutting flange 18 and a. hook 14-which is connected with the triangular baselO by means of angu-. larly disposed .webs 15 and 16, the tie abutting flange 13 beinga projection from and a part of the web 16. 'A web 17 intervenes between the web 15 and the tie abutting flange13.. V,

' The movable element E is. similarly formed. It'has a triangular baseiportion 18, a j awl9, adapted to engage the opposite edge ofthe base flange B from that engaged by jaw .12, and a hook20 connectedto the main body of the anchor by angularly disposed webs 21,. 22 between which-is a cross strut 23'; The element D has a tapered onwedgeformed rib 24, preferably acon-- tinuation of the base '10, which is engaged by hook 20, the interior surface of'the book ing themovable element over the other edge of the rail base and driving it towardthe tie as far as it'will go: This produces a wedging engagement between the pairs of wedges and hooks-.24, 20 and .25, 14, which draws the rail engaging jaws 12, 19 to-" gether', producing a powerful clamping action on the mill. The movable member may be driven by striking it with a hammer,

first on one end and then on the other. In this' way'there is no danger of twisting or skewing the parts of the device on the rail.

In most'anti-c'reeping devices ofthe wedge type the driven element can be reached by the hammer at' one 'end only so that atwistelf-1 ing or skewing of one part or the otheris likely to result when the free or movable member is driven toward the tie which, unless it is observed and lCOI'IGCtBCl by striking the other member, lessens or destroys the effectiveness of the hold of the device on the rail.

It will be seen that the parts of the device are' constructed so that they will be both light and strong. All needless metal is dispensed with. This is an important factor in the practical success of an article of this sort, put out in large numbers, because of the saving effected both in manufacturing cost and in transportation.

I claim:

1. An anti-creeper comprising two co-engaging members, one provided with a tie abutting part, and eachoprovided with a rail base engaging jaw formed below the plane of the bottom of the rail base with a laterally outstanding wedge-shaped rib adapted to be engaged by the other element.

2. An anti-creeper comprising two co-engaging members, one provided with a tie abutting part, and each provided with a rail base engaging jaw, formed below the plane of the bottom of the rail base with a later ally outstanding wedge-shaped rib, and with a hook adapted to'extend around the rib on the other member.

3. An anti-creeper comprising two oo-engaging members, one provided with a tie abutting part, and each formed with a rail base engaging jaw, with a wedging rib proj ecting outwardly from said jaw, and with a hook adapted to extend around the rib of the other member without embracing the aw thereof.

4:. An anti-creeper comprising two co-engaging members, one provided with a tie abutting part, and each formed with a rail base engaging jaw, with a wedging rib projecting outwardly from said jaw, and on ,the end opposite the jaw with a hook adapted to extend around the rib of the other member without embracing the jaw thereof.

5. An anti-creeper comprising two members having a wedging engagement with each other at opposite ends of the device,

each member being provided with a jaw extending around an edge of the rail base, and one of them with a tie abutting part; one of said wedging engagements being provided by a wedge formed rib projecting laterally from the jaw of one of said members and a hook on the other which engages said rib without embracing the jaw on which the rib is formed. 1

6. An anti-creeper comprising twoco-engaging members each formed with a jaw adapted to fit one edge of the base flange of the rail, a hook at the opposite end adapted to engage the other member, and with two angularly arranged webs which extend from the corners of said jaw respectively to the diagonally opposite ends of the book.

7 An anti-creeper comprising two co-engaging members each formed with a jaw adapted to fit one edge of the base flange of the rail, a hook at the opposite end adapted to engage the other member, two angularly arranged webs which extend from the corners of said jaw respectively to the diagonally opposite ends of the hook, and with a cross web in the space between said angularly disposed webs.

8. An anti-creeper comprising two co-engaging members each formed with a jaw adapted to fit one edge of the base flange of the rail, a wedging rib projecting laterally from said jaw, a hook at the opposite end adapted to engage the wedging rib oi the other member without embracing the jaw thereof, and with two angularly disposed webs which extend from the corners of the jaw respectively to the diagonally opposite ends of said hook.

9. An anti-creeper comprising two members having a wedging engagement with each other, one adapted to bear against a tie and the other to stand away from the same, one of said members being formed at one extremity below the plane of the bottom of the rail base with a laterally outstanding wedge-shaped rib and theother with a hook which engages said rib.

10. An anti-creeper comprising two mem bers having a wedging engagement with each other, one adapted to bear against a tie and the other to stand away from the same, one of said members provided with a base portion adapted to extend under and in contact with the base flange of the rail and with a jaw adapted to engage one edge of the base flange of the rail, said base portion extending beyond the jaw below the plane of the bottom of the rail base in the form of a wedge-shaped rib; the other of said members being provided with a hook to engage said rib.

11. An anti-creeper comprising two members having a wedging engagement with each'other, each consisting of a base portion extending under and in contact with the base flange of the rail, a jaw to engage one edge of said base flange, the base portion extending beyond the jaw below the plane of the bottom of the rail base so as to provide a wedge-shaped outstanding rib, and a hook adapted to engage, in each case, said rib formed on the other member.
